Present distribution networks have not been designed to accept extensive Distributed Generation (DG). The present framework may change in the near future impelled by a worldwide increase in DG penetration in distribution grids. The mutual dependency of energy distribution and communications on the same grid requires new means for effectively monitoring and(More)
We propose a new synchronized technique for Smart Grid. A PTP-Based IEEE 1588-2008 Global System has been defined. Specifically for PMUs with synchronism needs up to the microsecond range, for Energy Measurements System (EMS), for Intelligent Electronics Devices (IEDs) and for automated real-time control systems called Special Integrity Protection Schemes(More)

There is, at present, considerable interest in the storage and dispatchability of photovoltaic (PV) energy, together with the need to manage power flows in real-time. This paper presents a new system, PV-on time, which has been developed to supervise the operating mode of a Grid-Connected Utility-Scale PV Power Plant in order to ensure the reliability and(More)
The proposed technique integrates IEC61850 and PMU for extent of wide area measurement system (WAMS) with a new Synchronized Measurement Technology. This new Electronic Devices comprise three main technologies: a LM3S8962 microcontroller for PTP slave, a Single-Board-RIO for acquisition and synchronization and an IPC@CHIP based system for communications(More)
The aim of this paper was to design and develop a software application that enables users to perform an automated analysis of data from the monitoring of grid-connected photovoltaic (PV) systems. This application integrates data from all devices already in operation such as environmental sensors, inverters and meters, which record information on typical PV(More)
